Interactive tax on processor. Why not disk too?

Someone recently said that the interactive tax is not really a tax.  They 
just didn't give the interactive users the deep discounting they gave 
others on the newer processors.  Ok, suppose this is true, and the 90% of 
you who think this is BS temporarily coat it with honey and go on to the 
rest of this email.

Why don't they give people who are not using the i5 disk for interactive 
applications a break also?

In our shop a measly 9% of disk is used for "traditional" i5/os 
applications like our payroll, ERP, i5/os, etc.  By far a vast majority of 
it is used for:
  - Tivoli Storage Manager to back up clients and servers
  -  IXS card storage spaces
  -  Domino

Now, since he can buy a new Linux server with 500GB for less than the cost 
of 140GB of iSeries disk, the boss is thinking of forcing the archival of 
all Domino mail messages over a specified duration to a Linux based Domino 
server.  Since it is the cost of iSeries disk that is gagging us, you can 
bet your sweet aunt that we are not going to run this Linux server as an 
iSeries partition.
